This is a logical switch that spans one or more VMware ESX 4.0 servers. All the VEMs that form a switch domain should be in the same virtual Data Center as defined by VMware vCenter Server. This is the part of Cisco Nexus 1000V that actually switches data traffic. The network administrator configures the control VLAN.
The control VLAN is used to exchange control messages. One of two VLANs for the communication between VSM and VEM.
It runs on a virtual machine (VM) and is based on NX-OS. This is the control software of the Cisco Nexus 1000V distributed virtual switch. Table 5-1 lists the terminology used in the Cisco Nexus 1000V implementation. All the VEMs that form a switch domain should be in the same virtual Data Center as defined by VMware VirtualCenter.
Each server in the data center is represented as a module in the Cisco Nexus 1000V and can be managed as if it were a module in a physical Cisco switch. Troubleshooting VSM Modules Information About ModulesĬisco Nexus 1000V manages a data center defined by a VirtualCenter.Troubleshooting a Module Not Coming Up on the VSM.This chapter includes the following sections:
This chapter describes how to identify and resolve problems that relate to modules.
